Occupational lung diseases (OLD) including silicosis, asbestosis, and pneumoconiosis progress to end stage lung disease requiring lung transplantation (LT). Prognosis and treatment of OLDs are poorly understood and a paucity of data exists regarding LT outcomes. Additionally, transplant operative complexity for patients with OLD is high. Read More

Introduction: Clusters of silicosis cases have been reported in the fabrication of quartz conglomerate, a new high-silica-content artificial stone for kitchen and bathroom benchtops (countertops).
Aim: We describe two cases of accelerated-type silicosis with hepatic granulomas arising in workers exposed to artificial quartz conglomerates.
Methods: A confident diagnosis of multiorgan silicosis was based on high level of respirable silica in the workplace, typical radiological alterations in chest high-resolution CT, histological findings in the lung and liver, and detection of silica crystals in both tissues by phase-contrast polarising light microscopy and scanning electron microscopy and energy dispersive spectroscopy.

Background: Silicosis is a common occupational disease, characterized by silicotic nodules and diffuse pulmonary fibrosis. We demonstrated an anti-fibrotic effect of bone marrow mesenchymal stem cells (BMSCs) in silica-induced lung fibrosis. In the present study, we sought to clarify the homing ability of BMSCs and the specific mechanisms for their effects. Read More

Silicosis is one of the most prevalent occupational lung diseases and a public health problem throughout the world. Underground miners of copper and cobalt are exposed to the dust of these minerals and thus to the risk of developing silicosis. The objective of this report was to describe a series of silicosis cases in miners exposed to mineral dusts at a mining company operating since the colonial era in Lubumbashi, Katanga province, in the Democratic Republic of the Congo (DRC).

Background: Work-place exposure to silica dust may lead to progressive lung inflammation culminating in the development of silicosis, an irreversible condition that can be complicated by onset of pulmonary hypertension (PH). The molecular mechanisms leading to the development of PH and lung fibrosis in response to silica are not well understood. Oxidant/antioxidant imbalance in the lung may promote fibroproliferation and vascular smooth muscle proliferation, ultimately leading to the development of PH. Read More

Background: Pulmonary fibrosis induced by silica dust is an irreversible, chronic, and fibroproliferative lung disease with no effective treatment at present. Previous studies have shown that early intervention with bone marrow mesenchymal stem/stromal cells (BMSCs) has positive effect on anti-pulmonary fibrosis caused by silica dust. However, early intervention using BMSCs is not practical, and the therapeutic effects of BMSCs advanced intervention on pulmonary fibrosis have rarely been reported. Read More

Workers chronically exposed to respirable crystalline silica (CS) are susceptible to adverse health effects like silicosis and lung cancer. This study aimed to investigate potential early peripheral biomarkers of inflammation and oxidative stress in miners. The subjects enrolled in this study were occupationally unexposed workers (OUW, n = 29) and workers exposed to crystalline silica (WECS), composed by miners, which were divided into two subgroups: workers without silicosis (WECS I, n = 39) and workers diagnosed with silicosis, retired from work (WECS II, n = 42).

To study the role of pirfenidone in rats exposed to silica dust, we established the rat silicosis model with 50 mg/ml silica by intratracheal instillation. From the first day after silica instillation, rats were given pirfenidone (50, 100 mg/kg/day) and rats were sacrificed at 14 days and 28 days to observe the histopathology of lungs, to analyze the level of TNF-α, IL-1β, IL-6 in lung tissues and to measure the expression of TGF-β1, Smad2/3, vimentin, and E-cadherin in lung tissues. Results showed that pirfenidone (50, 100 mg/kg/day) reduced the silica-induced alveolar inflammation, the damage of alveolar structure and the blue areas of collagen fibers in the lungs of rats.

Background: Silicosis, a progressive inflammatory lung disease attributed mainly to occupational exposure to silica dust, shows loss of lung function even after cessation of exposure. In addition to conventional evaluation methods such as chest X-ray, computed tomography, and spirometry, we identified heme oxygenase (HO)-1, an inducible antioxidant, as a potential biomarker to identify at-risk patients. We found that HO-1 was critical in attenuating the disease progression of silicosis; however, the key signaling pathway has not yet been elucidated. Read More
